How to Count Days Between Two Dates
To count the days between two dates, the calculator computes the difference in milliseconds and converts it to days. This day counter performs a precise calculation including leap years and displays the result in multiple units: days, weeks, months, and years.

Frequently Asked Questions
Does the counter include the start and end dates?
The counter calculates the difference between the two dates. If you need to include both the start and end dates, the result would be one day more than what is displayed.
Can I calculate business days excluding holidays?
The business days calculation excludes Saturdays and Sundays. Holidays are not deducted as they vary by country and region. For US-specific business day calculations including federal holidays, try our Business Days Calculator.
